Using the following as a reference:
I’m trying to build some charts and I need to call a .jar file from
within my controller. Here’s my code:
pipe = IO.popen("java -jar /raid/projects/Dashboard/charting/
This gives me nothing, however, if I run the command via the command
line then it returns the images I need.
I’m running Rails through JRuby on a Sun Solaris machine if that helps
